To all whom it may concern:

Be it' known that I," 'JOSEPH H. FLETCHER,

a citizen' of -the United States, residing at Seattle, in the county ofKing and State of Tire-Shield, of which the following is aspecification.

. This invention relates `to detachable shields or-:treads for pneumatictires and its object is to providea simple, durable, andeiiicientdevicepf this character which' can be readilyattached to orremoved from a wheel and tire, said device being designed Vfor use 1nconnection with clencher Vor other forms of pneumatic tires.

Another object is to provide a composite tread or shield made up ofbands of leather and fabric so connected as to prevent injury to the'tire eitherfrom puncture or abrasion.

Another object is toprovide novel means on. the tread'for preventing thetire or u W eel from skidding or slipping, said means -being so'fastenedto the tread as to be securely retained. thereon no matter to whatextent they' may be worn as a result of use.

Withtheseand other objects in view the invention consists of certainnovel features of construction and combinations of partswhich will behereinafter more fully-*de scribed and pointed out in the claims'.

In the accompanying drawings is shown the preferred form of theinvention.

`n saidv drawings :,'Fi'gure' 1 is a side elevation of a -portion of -atire showing thel tread ap lied thereto. Fig. 2 is a section on -linaAf- Fig. 1.v Fig. 3 is a plan view .of

ae portion of the tread or shield shown in Fig. 1. Fig.V 4 is a planView of the inner surface' of a portion 'of said shield. Fig. 5

is'an enlarged section on line C-.D Fig. if Fig. 6 is aview similarl toFig. Sand showing a slightly modified formvof shield.

AReferrin to the figures by characters of reference, designates theclencher rim of a wheel and designates apneuinatic tire engagingv the;sam`e. The shieldv or tread used for' protecting the tire consists of athey may be worn.

' rality. of

fing 2 y plates has a hook means of a suitable clamp 1 lining .for theband 1 and also for the wings 2. Retaining strips 3 of leather arearranged upon the 'inner surface of the .lining 2 anddinder oppositeside Aportions of the band 1. These strips are engaged by the y innerheads of rivets 4 extending through outer band. preferably' formed ofheavy leather and which is engaged by the outer the bands 1- and 2 andalso through an heads' of the rivets 4. These rivets, as in v dicated inFig. 1, are disposedfat regulart'er of the shield.

Rectangular studs G are arranged. upon the outer-surface of the band 5and along diag- 'onal lines and each of these studs has a tapered bore 7engaged by the frusto-conical .head Sof a rivet 9. These rivets extendthrough the bands lfand 5 and the inner heads'lO are lapped 'andconcealed by the lining 2. "It will be apparent therefore that the heads8 will serve to .retain the studs upon the band 5 no mattei` to" whatextent As shown particularly in. Fig. 5 each strip 3 has the inner,heads of rivets 4 pressedv thereinto or seated .wi-thin Iintervals andextendthroughout the dianie f countersinlzs4 11 so that the headsarevthus not abrade or otherwise injure it. A plufolds ofthe lining 2along the center thereof for the purpose of fastening the folds to-Secured between the wings 2 an'dthd-lin at one side ofthe shield areplates fastened in place by means Y any other preferred manner andextending vrivets 12 are secured within the held out4 of contact Withthetire B and. can

Plates. 16 are securedbetween the wingsV and their. linings at the other side ofthe shield andeach ofthese v 17 extending'from it and beyond the Wings The hooksare",designed to be engaged bya rope or cable 18, the. ends ofwhioh lapand are' adjustablyseeured by A shield. suchas above escribed isdesigned particularly for use-.upon Velencher tires.`

it is to be understood', however, that where no clencher rims areutilized hooks 20:

'similarto the hooks 17 can? be securedto the wings" at both sides ofthe shield 'asindicatedin Fig. 6. lVithlthis construction a separatecable or binding device is providedat each side o'flithe wheelfBreach-set of hooks;

In applying the shield to a clencher tire .l the .hooked Hanges l5 are-rst placed'into engagement with the rim A as shown in Fig. 2, afterwhich the shield is placed over Ythe .faceof the rivets ety are arrangedwithin depressions so that they do not contact with the tire. Tlierivets 14 have their inner heads rounded so that they Willlnot injurethe surface of the tire and this isiespecially, unlikely because theseheads are not pressed t0 any extent against the tire.-`

Importance is attached to thenpafrticular arrangement of the studs 6 andthe means.

utilized for fastening them in position. As heretofore stated 4byprovidin the tapered 'rivets' 8 the studs can wearV own any distanceWithout becoming loose. It will be noted that the studs are arranged sothat their .sides extend along da onal lines.

Some of the `corn'ers of the stu s 6 are eX- tended in .the direction oftravel of the wheel while the remaining corners are extended laterally.yIt will be seen therefore that the studs will readily bite intotheroadbed over which the wheel is traveling and prevent the Wheel fromslipping either inthe direction of its travel or laterally.

Vhat is claimed is:

1. A tire shield comprising outer and inner flexible bands, laterallyextending wings integral with the inner band, a lining upon the innerband and its wings, parallel strips separate from and secured upon thelining and extending circumferentially within the shield, said stri sbeing also separate from the ybands andp having depressions therein,rivets extending through the strips, bands and lining, for binding themtogether, saidrivets being seated at one end within the depressions andheld-by the strips out of contact with the Itire Within thex shield, andflexible means for binding. the wings' upon a tire.

2.. A tire' shield comprising louter and Wings and concealin the innerends of saidl tapered means, para lel strips secured upon the innersurface of the lining and-extending circumferentially within the shield,said strips being separate from the lining and 'the bands and havingdepressions therein,

means extending through the strips, bands,

and lining for binding them together, saidl means being seated at oneend in the depressions and held by the strips out of con; tact withthetire within the shield, and flexible means for binding the Wings upon atire.A`

In testimony that I claim the foregoing as my own, I have heretoa'tlixed my signature in thev presence of two witnesses.
